Title: Developing device and image forming device
Inventor: MASUDA TSUNEJI
IPC: G03G15/09
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To make it possible to uniformly coat a rotary developer carrier with two-component developer of which carrying force is lowered over a long term by setting the normal direction component and the tangential direction component of the flux density of a magnetic pole regulating the amount of the developer at the position of a developer layer thickness regulating member to specified values. SOLUTION: For setting the napping direction of the developer 11 in the vicinity of a blade 5 as near as possible to the normal direction of the surface of a developing sleeve so as to make the developer 11 in a dense state, the direction of magnetic flux M at the position closest to the blade 5 is made to be >=60 deg. and <90 deg., that is, the values of the normal direction component Br and the tangential direction component Bs of the surface of the sleeve of the flux density are set to 0<Bs<Br<2/3. When an angle formed by the direction of the magnetic flux M of the pole S2 passing the position near to the blade 5 with the tangential direction of the developing sleeve 4 is, for example, α3=70 deg., the developer 11 in the vicinity of the blade 5 is perfectly made in the honey state, whereby the stable coating by the developer is realized.  Thus, faulty coating is not caused and an excellent image is always stably obtained.

Abstract: PURPOSE:To prevent a damage by having a first interlocking means capable of moving a printing unit so as to be detached only when a press-fitting plate is in an open position and a second interlocking means inhibiting the press-fitting plate from returning to a press-fitting position when the printing unit is detached. CONSTITUTION:A photoprinting device is designated such that a worker can turn an ink ribbon cassette 38 and a printing head 44 with a rotary bracket 32 in the direction of an arrow F to a position they can be detached and pull out the ink ribbon cassette 38 forward to replace it with a new ink ribbon cassette 38. When the ink ribbon cassette 38 is loaded again after replaced by the worker, the semicircular notching 76 of a latch arm 72 is engaged with a lock pin 78 by the energizing force of a torsion coil spring 74 so that the ink ribbon cassette 38 is maintained to remain loaded. At the same time, a ring 54 is pressed by the notched part 32A of the rotary bracket 32. As a result, its leading part is extruded from the through hole 52B of an L-shaped bracket 52, and the press-fitting plate 18 can be turned in a direction A. Collision in an intermediate part due to moving simultaneously can be thereby prevented.

Title: Photographic printing device
Inventor: SHIODA KAZUO
IPC: G03B27/32
Filed: 1987-06-19
Abstract: PURPOSE:To effectively utilize a light beam and to shorten a printing time by narrowing the deflection angle of a raster at the time of printing a photograph with a deflection angle switching means of the raster and making a CRT emit a light in a size corresponding to the screen of a film. CONSTITUTION:When a controller 22 receives a printing command, it connects switches 24 and 25 to a contact (b) and actuates a synchronizing signal generation circuit 26. The circuit 26 generates a synchronizing signal whose synchronism is short and inputs it in a 2nd deflection control circuit 33, which outputs vertical and horizontal deflection signals and sends them to the deflection yoke 31 of the CRT 16 through the switch 25. The deflection angle in the light emission area of the CRT 16 is narrowed corresponding to the size of a photographic film. Then, the number of times of scannings by an electron beam per a unit time is increased and the luminance of light emission of the CRT is enhanced. Thus, the light beam of the CRT can be effectively utilized and the time for printing a photographic picture can be shortened.

Title: Amorphous semiconductor solar battery
Inventor: MORIUCHI SOTA
IPC: H01L31/04
Filed: 1990-06-11
Abstract: PURPOSE:To improve curve factor while suppressing voltage factor loss and maintaining release voltage high by narrowing the band gap at one part in the i layer caught by a p-layer and an n-layer as comparing with other band gap in the vicinity. CONSTITUTION:In an i-type a-SiGe layer 12, a region where a band gap is narrow is made by temporarily changing, for example, the flow of GeH4 to the flow of SiH4. Since the flow of GeH4 is 0 on the side of n-type a-Si layer 11 at the left of the layer 12, the band gap (Eg) is 1.75, and then if the flow of the GeH4 increases, it drops gradually, and when the ratio of the flow of GeH4 to the sum of the flows of SiH4 and GeH4 is 20%, it becomes 1.45 eV. Next, when the flow of GeH4 drops, it increases gradually, and it becomes 1.75 eV at the part in contact with the layer 13. The distance for the generated positive hole to shift to the layer 13 is shorter to provide the narrow region of Eg in the vicinity of the interface to the layer 13, so the collection efficiency to the positive holes increases, therefore curve factor improves and photoelectric transfer efficiency can be improved.
